It's no secret that the Big 12 is college football's best quarterback conference. As things move closer to the start of fall camp, Huskeronline.com will begin our comprehensive positional rankings of the entire Big 12. Today we start our ranking lists with the quarterback position.

1. Sam Bradford, Oklahoma, 6-4, 220, Jr.

Junior Oklahoma signal caller Sam Bradford is the returning Heisman Trophy winner in college football and arguably the potential No. 1 pick in next year's NFL draft. Bradford set an NCAA record in passing efficiency with a rating of 180.8 and he threw for 4,720 yards and 50 touchdowns as a sophomore. The big question this season will be if Bradford can put up those kind of numbers with four new starters on the offensive line and two new wide receivers.

2. Colt McCoy, Texas, 6-3, 210, Sr.

One could argue that if Texas would've played in the Big 12 championship game instead of Oklahoma Colt McCoy would've won the Heisman Trophy over Bradford. McCoy passed for 3,859 yards and 34 touchdowns, and he also was Texas's leading rusher with 561 yards and 11 touchdowns. McCoy is one of the grittiest players in all of college football and there's no question he'll push Bradford and Florida's Tim Tebow for the Heisman Trophy this year.

3. Todd Reesing, Kansas, 5-11, 200, Sr.

It's hard not to like Kansas quarterback Todd Reesing. The toughness and heart alone he showed in last year's game in Lincoln won over several Husker fans—including NU head coach Bo Pelini. With both his top wide receivers back, Reesing should be able to better the 3,888 yards and 32 touchdowns he threw for in 2008. What probably hurts Reesing compared to Bradford and McCoy is his overall lack of size, but he makes up for it with his great awareness and leadership skills on the football field.

4. Zac Robinson, Oklahoma State, 6-3, 220, Sr.

The biggest advantage Oklahoma State quarterback Zac Robinson has is he arguably has the best supporting cast on offense in the country. Robinson has a running back in Kendall Hunter that rushed for 1,555 yards in 2008 and a big play threat at wide receiver Dez Bryant. To go along with Hunter and Bryant, Robinson also has an outstanding offensive line led by future first round draft pick Russell Okung. As a junior, Robinson threw for 3,064 yards and 25 touchdowns to go along with 562 yards and 8 touchdowns rushing. OSU's season opener in Stillwater against Georgia will definitely be must watch TV for Big 12 football fans.

5. Robert Griffin, Baylor, 6-3, 200, So.

I like Baylor quarterback Robert Griffin as much as anybody, but it's hard to put him over the other quarterbacks in this league until he wins more games. Griffin gave up running track this year, which should really help his development. We'll know right away how much better Griffin will be this season in Baylor's first two games of the year against Wake Forest and Connecticut. Probably the most impressive stat for Griffin in 2008 was the fact he threw just 3 interceptions on 267 passing attempts.
